A dynamic extension for LgV controllers

A dynamic state feedback control stmcture is proposed in this paper. The scheme is conceived as an adaptive controller with the equilibrium in an LgV control law as the uncertain parameter, which allows the implementation of the controller for systems with unknown equilibnum. A new property of LgV controllers is given, and it is proven that this and other important properties carry on to the proposed scheme. A synchronous machine case study shows that the pmposed scheme may give hetter results than the L,V controller from which it is derived. Zndex Terms-Dynamic feedback, passivity, stability domains.
